Bug taxonomies help in providing fast and effective feedback so that they can easily identify possible reasons for failure of the software. Using bug taxonomy, a large number of potential bugs can be grouped into few categories. Whenever a new bug is reported, using bug taxonomy, a tester can easily analyse and put that bug into any of these categories. At the end of testing, testers can understand the type of categories of bugs that frequently occurred and thereby in successive rounds of testing he can focus on writing more test cases that would help to detect such bugs. In addition, test leaders can guide their testers to focus on such frequently occurring bugs.
Bugs are difficult to categorize. Though there is no universally correct way to categorize bugs, it is recommended to adapt some taxonomy to categorize bugs. This would help in test strategy. By understanding distribution of bugs in each category, we can pick bug category that has more number of bugs, focus on it , and take corrective and preventive measures to address. While implementing test related processes in the organization, one can chose a taxonomy given by Boris Beizer or by Orthogonal Defect Classification or by IEEE taxonomy specified in IEEE87B.

80 % of the total bugs in the software will find out in 20 % of the testing time
Software goes through rigorous beta testing to prevent serious bugs. Since you cant duplicate what everyone is going to do, the developers obviously expect some bugs.
"Testing shows the presence, not the absence of bugs." - Edsger Dijkstra
By testing beta software, and reporting any bugs/issues to the manufacturer.
Software testing is a cyclical process in which you: plan a test execute it identify bugs fix them test again During this process is you change the application or software you update the testing plan. This you have versions for the testing plan so that you can see what did the previous test check.
software is process to finding error ,bugs and validation against requirement.testing involves operation of the system.
One of the best reasons to test software is to evaluate whether the software performs as you would expect it to perform. Software is tested in many different situations: - Testing during development (test-driven development, ...) - Testing before delivery to the customer - Testing performed by the customer before buying (a trial, demo etc.) - Testing done by the customer during use of the software When writing software it is almost impossible to avoid introducing bugs (misbehaviour) into the programs. Testing helps find these bugs and helps improve the software. More testing: - Testing whether the software conforms to a specification - Testing whether the software is compatible with some other software ...
without it, there is no measure for how effective the end implementation is. Testing is used to identify and improve upon the solution on the next iteration of the cycle, attempting to erradicate any bugs which may harm the performance / uptake of the mentioned piece of software.
Regression testing is a type of software testing that seeks to uncover new software bugs, or regressions, in existing functional and non-functional areas of a system after changes such as enhancements, patches or configuration changes, have been made to them.
Software Testing is the process of evaluating and verifying that a software application or system meets the required specifications and is free of bugs or errors. It involves executing the software with the intent to identify defects, improve quality, and ensure that the final product is reliable and performs as expected.
Alpha Testing: Alpha testing is testing of an application when development is nearing completion. Minor design changes can still be made as a result of alpha testing. Alpha testing is typically performed by a group that is independent of the design team, but still within the company, e.g. in-house software test engineers, or software QA engineers.Another DefinitionAlpha testing is final testing before the software is released to the general public. First, (and this is called the first phase of alpha testing), the software is tested by in-house developers. They use either debugger software, or hardware-assisted debuggers. The goal is to catch bugs quickly. Then, (and this is called second stage of alpha testing), the software is handed over to us, the software QA staff, for additional testing in an environment that is similar to the intended use. Beta Testing: Beta testing is testing an application when development and testing are essentially completed and final bugs and problems need to be found before the final release. Beta testing is typically performed by end-users or others, not programmers, software engineers, or test engineersAnother Definition:- Following alpha testing, "beta versions" of the software are released to a group of people, and limited public tests are performed, so that further testing can ensure the product has few bugs. Other times, beta versions are made available to the general public, in order to receive as much feedback as possible. The goal is to benefit the maximum number of future users.
